But, There are already a whole bunch of laws addressing that!
Firearms in the wrong hands are also a threat to community safety
Solid first steps would be to close the gun show loophole that allows the sale of guns on a cash and carry basis, with no identification required. Add those who commit crime(s) with a gun to the Predatory Offender Registry, and require them to register where they live and when they move, as we now do with sex offenders and other predators. And we should enact an assault weapons ban.
So if we harass, constrain, control, and limit the law abiding citizen, we might some how control those who live outside the law??
